Many systematic reviewers choose to use reference management/bibliographic software to manage the references that they retrieve from the different databases. There are many different programmes that you can use, each with strengths and weaknesses.
NHS staff who are alumni of King's College London will have alumni access to RefWorks (if you are an alumni student email email@example.com for details of how to access Refworks).
Other programmes which you may hear of include Mendeley, Zotero, EndNote Web, CiteULike and Papers for the Mac. Many of these are free (although you may be asked to pay for some advanced features).
The King's Guide to Referencing has a short quiz you can take to get a suggested piece of referencing software:
Key features for systematic reviewers:
When reading systematic reviews you may see mention of two tools commonly used by Cochrane systematic reviewers and others: Covidence and RevMan. If you are undertaking a systematic review you may have them recommended to you by a supervisor or colleague. Whilst King's does not have an institutional subscription to these tools at this stage there are free trial versions available to download and some departments/divisions or research groups may have purchased access independently.
Please note that many systematic reviews (particularly ones which are smaller scale than the standard Cochrane ones) are successfully completed without using these tools and there are also other products available.
